1、java一行一行写入或读取数据假如E:/phsftp/evdokey目录下有个evdokey_201103221556.txt文件，现在对evdokey_201103221556.txt文件进行写入或读取操作，并解决写入或读取出现的乱码问题。 文件内容如：zhangsan,23,福建
lisi,30,上海
wangwu,43,北京
laolin,21,重庆
ximenqing,67,贵州 代码如下：/**
*一行一行读取文件，适合字符读取，若读取中文字符时会出
2、现乱码
*
*流的关闭顺序：先打开的后关，后打开的先关，
*否则有可能出现java.io.IOException:Streamclosed异常
*
*@throwsIOException
*/
@Test
publicvoidreadFile01()throwsIOException{
FileReaderfr=newFileReader("E:/phsftp/evdokey/evdokey_201103221556.txt");
BufferedReaderbr=newBufferedReader(fr);
Str
3、ingline="";
String[]arrs=null;
while((line=br.readLine())!=null){
arrs=line.split(",");
System.out.println(arrs[0]+":"+arrs[1]+":"+arrs[2]);
}
br.close();
fr.close();
}
/**

@Test
publicvoidreadFile02()throwsIOException{

BufferedReaderbr=newBufferedReader(isr);
//
5、简写如下
//BufferedReaderbr=newBufferedReader(newInputStreamReader(

String[]arrs=null;

System.out.println(arrs[0]+":

}
br.close();
isr.close();
fis.close();
}
